I just purchased two 12 inch GT5s, Jeff recommended them to me. Found a decent 650w rated amp @ 2 ohms for $110.00 they are in a small sealed box, but I am going to put them in a custom ported box soon. Pretty satisfied so far. By the way, they aren't 'boss status' far from it. Boss is almost incomparable to anything else. These JBLs are not the best, but for $50 bucks a sub, they are pretty decent. 275w power handling, but most speakers can actually take a bit more than rated if feeding them a clean unclipped signal. pretty good motor force for such a cheap lower power handling sub, play low enough for his tastes, and don't require a huge box. He wants a budget sub. If he wanted a non-budget sub he would of asked. So saying 'spend this much more money and get...' is useless to him. hes fitting a budget, aswell as matching power handling to his amp.
